One gang twin switch including intermediate

[IJWS15]

Looking for a twin switch with at least one intermediate (not worried if it is two) but those I can find, including grid switches, all have rounded faceplates.

Can anyone point me at one with this profile as everything also in the house looks like this (although way older)

You should be able to use CLICK POLAR.
(Not Click Mode - it's curved.)
The switch modules can be removed very easily, and you should be able to
a) buy a regular 2 gang 2 way switch, and a regular 1 gang intermediate switch, and alter them.
b) or buy most of the separate parts, and build it up.
